-- Information about the crash:
- Custom settings of the application:

Plasma runs fine as long as I don't have the Microblogging widget configured; if I configure it with my Twitter login, and save that to Kwallet, then next time I log in, Plasma crashes. So it might actually be Kwallet and not the Microblogging widget that's causing trouble.

The crash can be reproduced every time.
